Do-it-yourself sip-panel house. Country house from sip panels How to properly assemble a house from sip panels

Instructions for assembling a house from sip panels. SIP Houses are produced at the SIP 47 plant as a house kit, that is, a set of board elements and sip panels, made with high precision based on the project chosen by the customer. The sip panel house kit can only be assembled at the construction site like a children's designer. All products are marked, and a wiring diagram is attached to the set of elements, guided by which mounting sip panels. Before starting work, you need to study the wiring diagram and check the completeness of the package.

In order to better understand the features of installation, it is necessary to have an idea about SIP panels.

Basic tool that you will need for self-assembly of a SIP house:

Screwdriver (assembly on self-tapping screws) / nailer (assembly on nails);

Chainsaw;

Circular Saw;

Roulette;

Building level;

Thermoknife for sampling the groove in SIP-panels.

Panel design and typical dimensions

SIP panel(structurally insulated panel) is a building product that includes two OSB (oriented strand) boards with an insert of insulation - expanded polystyrene (EPS) between them, connected and pressed with a special adhesive under a pressure of 20 tons. This structure allows the panels to perform a dual function - they serve not only for heat and sound insulation of enclosing structures, but are also able to withstand significant compressive and bending loads. Therefore, these products are suitable for the construction of any kind of buildings. They are used for walls, partitions, as floor slabs and roof coverings.

Typical dimensions of SIP panels

The thickness varies in such sizes from 68 mm to 244 mm. Often used sip panel with a thickness of 174 mm (with a thickness of PPS 15 cm, OSB 12 mm) width 1,250 m; length from 2.5 m to 2.8 m.
For the construction of enclosing walls, standard 17.4 cm sip panels are used, for ceilings and roofs - 17.4 - 22.4 cm thick. Products 12.4 cm thick are used for partitions in the house.
Sip panels are light - no more than 20 kg / m 2, which allows them to be installed by two, three people and without the use of a crane, and are also easily processed and cut with a hand-held power tool.

Assembly procedure for SIP at home

The assembly of SIP at home consists in the sequential execution of the following operations:

Foundation devices and installation of the lower trim;
Installation of the basement;
Installation of walls of the 1st floor;
Assembly of interfloor ceilings and walls of the next floors in the case of a 2-3-storey building;
Installation of attic floor, attic, SIP roof.

Foundation device and installation of the lower trim

Foundations can be monolithic tape, pile, and design in the form of a monolithic ribbed slab. The type of foundation should be selected based on the properties of the soils underlying the structure at the construction site. When choosing the type of foundation, it is recommended to use a pile foundation- the most suitable for the simplicity of the device, relatively low cost, the possibility of application under most types of soil conditions and the convenience of combining with the base of the structure of the prefabricated SIP house.

To support the harness on top steel pipes protruding above the ground surface, special heads with a horizontal metal plate are installed, or a steel beam can be laid from the channel with the shelves up. In the latter case, the strapping beam is attached to the steel beam with anchors every 50 cm. designs SIP at home. The strapping beam is attached to each pile with self-tapping screws "grouse" having a diameter of up to 12 mm.

The strapping beam must first be impregnated with a fire-retardant composition, and a gasket made of bituminized paper, roofing felt or other rolled waterproofing materials. In the case of laying the support beam on a metal beam or on a strip or slab foundation waterproofing must be laid under the entire lower surface of the timber.
The strapping beam is installed exactly according to the markings corresponding to the layout of the SIP house and its assembly scheme.

At the corners and intersections, the elements of the timber are combined with each other by staples and fastened with self-tapping screws 8x180 mm. Fasteners on the brackets are time-tested, the brackets withstand heavy loads and do not burst. They give additional rigidity and strength in critical areas.

In the event that the support beam is laid on the horizontal concrete surface of other types of foundations, it is attached anchor bolts, which must be buried in the body of the foundation by at least 100 mm in increments of 500 mm in length.

Plinth cover installation

After installation and fixing to the foundation of the lower support beam, a SIP floor is mounted on it, including: wooden beams-logs 100x150, connecting inserts between the panels from a bar with a cross section of at least 50x150 mm and a sip of the floor panel. Logs are installed in the grooves available in each sip panel along the perimeter. First, the first sip floor panel is laid at any of the corners, the groove at the end is filled with foam from the mounting cylinder. A short connecting beam with a section of 50x150 is inserted into this groove, which is fastened through the sheathing of OSB-board with screws 3.5 mm in diameter and 40 mm long on wood every 15 cm in length. Then a groove is foamed at the end of the second sip panel, and it is joined to the first sip panel. In this case, the protruding part of the connecting beam enters the groove of the second product and is also fastened with screws for woodworking through the skin.

How many screws do you need for one SIP panel? In increments of 15 cm, on average, 100 pieces will be needed per panel 2500x1250 mm. self-tapping screws, half 600x2500 mm 80 pieces.

After connecting and fixing the first row of socle sip floor panels to each other along the extreme span of the sip house, located near the end wall, a lag-beam is installed along the entire length of the span. Before this, the grooves of the products are filled again assembly foam and the beam slides into this groove.

The subsequent assembly of panels, connecting bars and installation of the log is carried out in a similar way until one continuous plane of the floor sip is formed. To fasten wooden beams to flat floor products, wood screws with a diameter of 4.2 mm and a length of 75 mm are used. In places determined by the installation scheme, reinforced beams and timber are installed. The entire overlap is fastened through the logs to the strapping beam with self-tapping screws measuring 8 x 280 mm.
The resulting open ends of the sip floor of the first floor of the house are sewn up with a board having a section of 100 by 150 mm from all sides.

Installing the walls of the 1st floor

Design the first floor of a house made of sip panels is a frame consisting of wooden racks and wall SIP parts, fixed to the lower strapping beam, racks, and fastened together. At the initial stage of assembling the enclosing structures of the walls of the first floor of the sip house kit, boards are placed under each wall with a section of 25x150 mm on a solid basement floor, the layout of which must correspond to the design layout and wiring diagram. Strapping boards are attached with self-tapping screws with a diameter of 4.2 mm and length 75 mm to the overlap every 40 cm. The marking for laying the strapping must be done with maximum accuracy without deviations from the scheme, so as not to cause difficulties in the future. It should be noted that between the edge of the basement there should be gaps that match in thickness with the sheathing of the sip panel from the OSB board - 12 mm, which is indicated in the wiring diagram. Strapping boards are laid without gaps in places corresponding to the location of openings for installing doors in order to increase the accuracy and speed of their installation. In the future, after mounting the sip wall panels, cutouts are made in these places, so this must be taken into account when placing self-tapping screws. The main stage of wall assembly can be started from any corner of the SIP at home, where a vertical post is first installed, having a cross section of 100 by 150 mm, which is attached to the bottom binding board with two self-tapping screws with a diameter of 4.2 mm and a length of 7.5 mm, the first panel is mounted to it.
Further, on one of the corner sip panels, the side groove is filled with mounting foam, then the product is placed in the design position with fastening to the rack. In this case, the rack should fit snugly into the side groove of the sip panel. After checking the vertical position of the element using a plumb or level, the panel is attached to the binding board along the bottom edge and the stand with galvanized wood screws with a diameter of 3.5 mm and a length of 40 mm on each side from the bottom and along the side edge after 15 cm.
In the same way, another vertical beam and a second flat wall product are installed, adjacent on the other side to the corner of the house. After checking the verticality, both corner wall products are additionally fixed to each other by means of structural self-tapping screws with a diameter of 8 mm and a length of 200 mm in increments of 50 cm in height.

Starting from the first corner sip panels, racks and ordinary sip panels of external and internal walls are sequentially mounted in each direction. Before mounting each element, the side grooves are foamed, the sip panels are attached along the side edges to the vertical bars and from below to the strapping with screws 3.5 mm in diameter and 40-45 mm long every 15 cm on both sides.
At the corner nodes and T-shaped joints of the walls, the products are additionally sewn together with structural self-tapping screws with a diameter of 8 mm and a length of 230 mm every 50 cm in height. The installation of the walls is completed at one of the corners, in the reverse order to the installation of the first corner - a vertical bar is inserted into the side edge of the last SIP panel, pre-filled with polyurethane foam, covering the end part of the wall. The SIP panel is attached to a vertical beam and strapping with self-tapping screws with a diameter of 3.5 mm and a length of 40-45 mm in increments of 15 cm on both sides.
Next, two corner sip panels are pulled together with structural self-tapping screws with a diameter of 8 mm and a length of 230 mm in increments of 50 cm in height. The last operation to install the walls is to connect them with an upper strapping board. To do this, the grooves on the upper ends of the installed sip panels are filled with polyurethane foam, after which the strapping is laid in them. board with a section of 25x150 mm, which is fastened with self-tapping screws with a diameter of 4.2 mm and a length of 75 mm to vertical posts, then all wall sip panels are attached to it with screws with a diameter of 3.5 mm and a length of 40-45 mm on each side with a step of 15 cm.

Installation of upper floors

If a house from sip panels is multi-storey, then after the assembly of the structures of the first floor, the installation of an interfloor overlap is carried out. All operations are performed similarly to the installation of the basement. Then the installation of the second floor is carried out in exactly the same sequence as the installation of structures first floors of the SIP house. Then everything is repeated on the next floor.

Installation of attic floor, attic, SIP roof

The final stage is the installation of the attic floor, after which it is constructed roof. When constructing the attic floor, wall sip panels of complex shape are used - trapezoidal and triangular, on which the details of the rafter roof rest. The roof includes a frame consisting of mullions, rafters, girders, mauerlat, elements of valleys and ribs at fractures, as well as special SIP roof covering panels. These products, when roof not gable, they can also have both a rectangular and a more complex geometric shape - trapezoidal or triangular, so you should first carefully consider the wiring diagram and outline the assembly order. In the event that the last floor of the SIP house is not an attic, then first a Mauerlat is installed from a bar with a section of 100x150 mm over the plane of the attic floor along the perimeter of the walls. Then racks 100x100 mm, combined with a ridge beam measuring 100x150 mm and rafters measuring 40x200 mm, resting on the ridge with the upper end and the lower part on the Mauerlat.

If the SIP roof is of a complex configuration, then the frame is supplemented with intermediate runs and details of the installation of valleys and ribs at the outer corners of the intersections of the roof planes. Mauerlat, ridge beams, girders and other details can have a trapezoidal section, which is given to them during the manufacture of the house kit at the factory in order to accurately fit all roof elements to each other. All elements of the roof frame are joined together by galvanized self-tapping screws 8x280 mm, one at each attachment point. If necessary, metal connecting plates with holes for screws are used in some places. After assembling the supporting frame of the roof, the installation of roofing sip panels is carried out, which are attached to the load-bearing elements in a similar way to the design of the fasteners used in the assembly of floors. If necessary, the edges of some panels can be cut with a power tool at certain angles on the construction site, for example, when it is necessary to form a ridge joint for joining two panels.

If you find it difficult to understand these installation instructions for sip at home, then we recommend that you contact the specialists of SIP 47-Sip Factory.

The construction industry is gaining momentum every day and improving. Thanks to these processes, it is possible to build a massive house of any number of storeys at minimal cost. Moreover, such a building will be of high quality. In addition, you can evaluate the high level of strength of the SIP video panel by watching the video in this article. In our article, we will get acquainted with the advantages and disadvantages of such a material, and how to build a house from sip panels.

The main advantages of SIP panels

Do-it-yourself construction of houses from sip panels is gaining momentum in popularity. Why is this happening? Sip panels in relation to other materials have the following advantages:

Attention! Such unique features make it possible to make almost any type of building out of Sip, from warehouses to country cottages.

The main disadvantages of buildings from Sip

In this section, we need to consider all the shortcomings of the material for building a house from vulture products passed without unforeseen problems:

Sip buildings are usually not oxygen-permeable, so they keep the air inside the building. The problem can be solved by regular airing of the rooms.
Construction work takes less than 7 days, during which the weather can change, so think about the drainage system in advance.
A low level of fire resistance requires high-quality electrical wiring and fire alarms.
In addition, the blind area should be made wider so that in winter it is easy to clean the path.

If you have already decided on the material, and this is Sip panels, then below we will consider how to build a house using Canadian technology with our own hands.

Building a house with your own hands

The construction of buildings from such material includes some stages of construction:

Preparatory stage;
Arrangement of flooring;
Wall installation;
Roof arrangement;
Finishing work.

Let's look at each stage of the work in more detail.

Preparatory work

Before proceeding with the construction of an object from SIP panels, it is necessary to perform the following series of actions:

The first thing we do is drafting a project. For this you can use finished project or do it yourself: a video on how to do this can be viewed below;
To perform the work, you need to purchase a hacksaw and a screwdriver.
For the construction of this type, the usual type of foundation is suitable, for example, a screw foundation.
Next, we perform waterproofing. To do this, you can use a two-layer roofing material.
We lay the laying of the strapping beam, which will serve as the basis for the floor.

We equip the floor

Now we can start laying the floor base. To do this, you need to use panels. We put them over the entire area of \u200b\u200bthe building, but before that, waterproofing should be performed. Either bituminous mastic or roofing material will help us with this. Each groove should be treated with a sealant - this is necessary for splicing the panels.

Attention! In order to fix the parts more strongly, you can use self-tapping screws, and then lubricate all the ends with a special agent.

We mount the walls

After the previous stages are completed, you can start building a frame house. To do this, follow these steps:

We mount the frame horizontally along the entire perimeter of the building. The lower strapping must be carried out in accordance with all existing standards.
Next, we install the corner panels, from which the following Sip products are attached in different directions.
In order to avoid distortions, it is necessary to use the building level.
The upper selections of panel elements must be treated with sealant.
After we proceed to the upper strapping.

Roof installation

With such a construction, there is no need to create a truss structure, since the structure is able to withstand heavy loads. Also, for this stage, it is not necessary to additionally perform steam and waterproofing. You can see in more detail on the video of building a house from sip panels. In general, the installation process of the roof is carried out in the same way as the installation of walls.

Finishing work

If the walls are made of Sip panels, then the building receives a large number of advantages over other types. So, they are characterized by a smooth and even surface. That's why Finishing work much easier to perform than for other materials. To do this, you can use drywall, while not mounting the frame. You can also use clapboard, siding, tiles or stones. You can attach finishing products using building glue.

Attention! Flooring can be created using parquet, tiles, linoleum and other options.

Having completed the construction of a building from sip panels, you can achieve a very stable and reliable result. Plus, the price will pleasantly please you.

Structural insulating panels (SIP) are used for the construction of frame low-rise residential, public and domestic buildings. Of these, residential 2-storey cottages with attics, garages, summer cottages, warehouses, cafes, small shops and office buildings are being built. For some reason, such technologies are called Canadian in Russia, although they have nothing to do with this country. The author of the idea is an engineer from the USA, Frank Lloyd Wright, who developed the design of a composite panel with honeycomb fillers in the 30s of the XX century. Lightweight and cheap designs immediately attracted the attention of enterprising American manufacturers of building materials, who began their mass production.

What is SIP panels for building a house?

After constant improvements, an optimal design was created, which is most widely used in Russia, America and Europe. This is a kind of sandwich of 2 OSB-3 (oriented strand boards) with a PSB-25 insulation glued between them (a plate of suspension non-pressed self-extinguishing polystyrene foam).

Plates can be made from various materials: steel, aluminum, asbestos cement. But the term SIP implies the use in the production of SIP panels outer cladding from sheets with wood products:

oriented strand board made of large-sized chips (most often pine) bonded under conditions of high temperatures and pressure with waterproof resins. The arrangement of chips in the outer layers is longitudinal, and in the inner layers it is transverse. The number of layers is 3, less often - 4-re. OSB 3 is manufactured for use in conditions high humidity at high mechanical loads, therefore more expensive than other varieties;
fibrolite boards containing wood fibers and Portland cement M500 in a ratio of 60 to 40;
moisture resistant plywood;
gypsum fiber sheets;
drywall.

The following materials are used as insulation in the manufacture of SIP panels:

expanded polystyrene foam;
polyurethane foam;
basalt mineral wool;
fiberglass.

Combining into a monolithic structure is carried out by cold gluing with polyurethane adhesives using a press that creates a pressure of up to 18 tons.

Reliable waterproofing is provided by waterproof processing of sheets in the factory.

After gluing, the products are placed on special tables, where they are cut to the required dimensions. Then, along the perimeter of the part, grooves are selected for laying connecting bars or boards. Indents from the edges of the OSB are taken from 25 to 100 mm, depending on the section of the elements that will be laid in the grooves to fix the structure during the construction of the building.

SIP panel dimensions

The dimensions of the products are determined by their purpose - for walls, ceilings, floors, roofs. The basic structures are those used for the installation of vertical structures of buildings.

Standard products are available in the following sizes in mm:

length - 2500 ... 2800;
width - 625 ... 1250;
thickness - 124, 174 and 224.

Main advantages and disadvantages

Any construction technology has its own advantages and disadvantages. Buildings built using SIP are characterized by the following advantages:

Durability ≥ 60 years, due to the strength of the material with long-term preservation of geometric stability.
Mechanical strength, well withstand longitudinal loads up to 10 tons per m2 and transverse loads up to 2 tons.
High seismic resistance, laboratory-tested for destructive earthquakes.
Light weight, average sq. m weighs 15 ... 20 kg. Therefore, there is no need to build expensive powerful foundations. They are easy to transport and unload.
Installation of SIP panels is easy to perform work that does not require special equipment, heavy lifting equipment and high qualifications of the performer.
Houses practically do not shrink, which makes it possible to perform finishing immediately after completion of installation work.
Environmental friendliness and safety of buildings for human health. Formaldehyde resins, which are part of the adhesive components, emit harmful volatile compounds in small quantities. But their concentration is not dangerous, which is confirmed by the relevant sanitary standards (sanitary safety corresponds to class E1).
Good heat and sound insulation performance.
Resistance to aggressive external influences, including biological ones (fungal or mold damage).
High factory readiness and ease of assembly with the absence of wet processes make it possible to build a house from SIP panels at any time of the year, regardless of weather conditions, in the shortest possible time.
Fire resistance provided by high-quality processing with flame retardants in the factory. Expanded polystyrene foam is a self-extinguishing material, so the spread of fire to nearby structures does not occur even in open fire conditions.
Affordable cost.

Available cons:

the need for an efficient supply and exhaust air ventilation system to remove condensate from the joints of the frame with the plates;
the low thermal inertia of the supporting structures of the fence, characteristic of all frame structures.

You can often find an opinion about the danger of small rodents entering the house. This is based on the existing attractiveness of foams for rodents to make their holes in it. But it must be borne in mind that the insulation is reliably protected from all sides by OSB sheets, and the interpanel seams are covered with antiseptic boards or bars.

There is also an opinion about environmental hazard and flammability. You can agree with this only when purchasing low-grade counterfeit products. Therefore, you should buy products only from trusted manufacturers who have earned credibility in the building materials market, and with the obligatory presence of quality certificates. It is recommended that you order products directly from factories or reputable dealers. stable high quality the products of the Egger and Glunz concerns differ. You can also note the quality of products of the following companies:

house-building plant "Bauen House";
construction company "EcoEuroDom";
factory of panel houses "Hotwell";
enterprises "Building Together";
company "SIP Atelier".

Building a house from SIP panels with your own hands

Composition and sequence of operations:

Foundation construction. Most often, pile-grillage, columnar-tape, slab or tape structures of a shallow foundation are selected. The work is carried out according to the traditional method.
The device of the lower strapping and floor. On top of the foundation structure, horizontal waterproofing is performed from 2 layers of waterproofing glued using bitumen-containing mastics. The beam is laid along the perimeter of the building under the future walls and load-bearing partitions. Fastening to the foundation is carried out with anchor bolts in holes pre-drilled in the tree, two anchors are placed in the corners, intermediate ones - in increments of 1.5 ... 2 m. dense wood. The strapping will also be the basis for the location of the floor logs, along which a regular wooden floor is laid. Laying guide boards on the strapping beam, the section is selected depending on the dimensions of the panels. The boards are fastened in increments of about 40 cm with self-tapping screws.
Assembly of SIP panels. Installation begins in the installation at the first corner of the 2 panels. It is important that an even vertical angle is provided, the evenness of laying all other elements will directly depend on this. Before installation on the guide board, the lower grooves are foamed, fastening to the board is done with self-tapping screws in increments of 15 cm. Before connecting the panels to each other, the vertical grooves are also foamed, fixed with self-tapping screws every 50 cm. The verticality of the installation of parts is controlled by the building level. All other panels are mounted in the same way.
Installation of the upper strapping beam. Foaming of the upper grooves and fixing the strapping with self-tapping screws.
Cutting window openings, the operation can be done in advance, which will be more convenient. The holes made are reinforced along the contour with bars.
Installation of floor beams with laying sip panels.
Roof installation. If an ordinary truss roof is being constructed from sip panels, then the grooves will serve as a support for the rafters. Fastening to the rafters of the batten and laying the roofing material. If necessary, the attic is insulated.
Wiring of engineering communications.
Finishing work. The evenness of the walls greatly simplifies the finishing, and any fasteners of finishing materials (lining, siding, blockhouse, drywall, porcelain stoneware, wallpaper or natural stone) are securely held in sip-plates.

The cost of pre-fabricated SIP from high-quality raw materials is high, for example, a 224 mm thick panel measuring 2.5 by 1.25 m from 12 mm OSB costs ≥ 3500 rubles. The production technology is not difficult, so you can make sip panels with your own hands at home. To carry out the work, you will need a small enclosed space (garage for a car, a barn or utility room).

Selection and purchase of necessary materials

You will need the following materials:

12 mm OSB-3 sheets. For each product you will need two sheets. It is important to have a hygiene certificate indicating the formaldehyde emission class E1.
High-quality polystyrene foam boards PSB-S-25 (35) with dimensions according to the dimensions of the SIP with a thickness for external wall panels 15…20 cm.
Non-toxic one-component polyurethane adhesive, it will take about 0.2 kg per sq. m of surface. The glue must be environmentally friendly, without the release of harmful components during polymerization, and it must withstand temperature fluctuations that are possible in your climate zone. Features of the adhesive and the conditions for its use are indicated on the packaging, you can consult with the sales assistant, explaining to him what the adhesive will be used for. TOP-UR 15 have proven themselves well; Macroplast UR 7229, Kleiberit 502.8.
Flame retardants and antiseptics for additional processing of finished panels.

It is impossible to save on the purchase of cheap materials, as this will directly affect the durability and quality of finished products.

Equipment and tools

SIP bonding must be carried out under pressure, in industrial conditions this value is 18 tons. You can make a simple press yourself.

Scope of work:

production of a solid base from rolled profiles or profile pipes a size slightly larger than the dimensions of the panels;
fastening of vertical racks of 50 mm profile pipe along the perimeter of the sides of the base with a step of 0.5..1 m. The height of the racks should allow laying 4 ... 5 panels under the press, pressing them down with the upper frame and installing jacks. The top of the extreme racks is equipped with mounting steel clamps, into which it will be possible to lay crossbars from 50 mm profile pipes;
assembly of the upper frame from shaped pipes, hinged on top to the racks located on one of the sides. For uniform pressure transfer to the plates, the frame is welded from longitudinal and transverse elements with a step of 50 cm. A small hand winch is used to easily raise and lower the frame;
two small hydraulic car jacks with a lifting capacity of ≥ 2 tons are required.

If manufacturing is difficult (fastening elements for welding) or the number of planned products is small, then vacuum pressing can be used.

Construction composition:

a sturdy table or workbench (dimensions as for a press) with side racks for fixing the position of the sheets (2 racks on each side are enough);
durable cover made of awning fabrics, hermetically glued with Cosmofen SA-12 glue. The dimensions of the cover should allow covering a stack of panels with its tight fixation along the perimeter;
Vacuum pump;
supply hoses.

After pumping out the air, a pressure of ≥ 1000 kg per m2 can be generated.

Of the tools you will need a spray gun or a notched trowel to evenly apply glue.

Sequence of work

Laying on the base of the OSB sheet.
Marking the position of expanded polystyrene, taking into account the necessary grooves for laying bars or frame boards during the construction of a building. Vertically, the gap from the edge of the sheets is from 2.5 to 5 cm, 25 mm is enough from above and below. Since the adhesives dry very quickly (≤ 10 minutes), it is recommended to mark up about 10 sheets at once. The lines are drawn with a marker or a simple pencil.
Cutting foam to size.
Applying glue to OSB with thorough coverage of the entire area.
Foam insertion with light pressure for tight fit.
Applying adhesive to foam.
The imposition of the top sheet of OSB. Work must be done carefully, but quickly, so that the glue does not have time to grab.
The process is then repeated until a stack of 5 panels is completed.
Pressing products. If a homemade press of the above design is used, then the upper frame is lowered onto the stack. Then the crossbars are laid in the clamps of the racks and the necessary pressure is created by the jacks installed between the frame and the crossbars. The piston output of the jacks must be the same. If the vacuum method is used, then the pressure is created by pumping air out of a well and hermetically fixed cover. The exposure time of products under pressure is about an hour.
Cleaning jacks, raising the top frame or dismantling the shelter from the cover. The panels are transferred to a flat surface and stacked. In this position, they are kept for at least a day to strengthen the adhesive joint.
The following stacks of products are made in the same way.

As you can see, the manufacturing process is quite simple, and the products will cost at least 2 times cheaper than factory designs. Careful observance of technology and the use of high-quality materials are guaranteed to ensure good quality.

The construction of houses from sip panels is a novelty in the domestic construction market. If a European has not been surprised by such houses for 50-60 years, then for Russian developers this technology is an occasion for heated discussions.

Sip panels are a structure made of polystyrene foam layer, enclosed on both sides in OSB boards. The internal heat and sound insulating layer can be of different thickness, it all depends on the future purpose of the panels. Thickened sip panels are bought for furnishing external walls winter buildings, and thinner panels are used for interior walls or for arranging summer houses.

Advantages of the technology of building houses from sip panels

The main factor in the high popularity of this material for construction is the proper level of its factory readiness. That is, when buying sip panels, the developer buys a product assembled according to technology and ready for use. At the construction site, it remains only to correctly assemble the box of the house itself, which eliminates the marriage that occurs as a result of excessive "amateur" of the developer.

Advantages of sip panels

In addition, build with panels frame house the customer can do it himself, while saving quite an impressive amount.

Under frame houses no complex expensive foundation is needed. Installation does not require a lot of manpower - everything can be done with your own hands, besides, you do not need to spend money on ordering special equipment, the panels are easy to carry by yourself.

Although frame houses have a significant number of advantages, panels for them are still produced by more than one manufacturer, there are a huge number of them, and each makes panels according to its own technology. So the assessment of the quality of the purchased material lies entirely with the buyer.

It is worth paying attention to the level of formaldehyde emission in the plates - it should be no more than E1 (this level is safe for humans). In addition, the inner layer of the board must be made of high quality self-extinguishing foam, polystyrene foam or polyurethane foam.

Despite the fact that the thermal protection of such houses is one of the advantages, it also has one significant drawback: the house functions like a thermos, because OSB boards, saving energy, do not allow water vapor to pass through. Therefore, frame houses need mechanical ventilation technology. A recuperator unit that removes air from living rooms and heats cold air masses coming from the street is well suited for these purposes.

The laying of the ventilation system in such houses is thought out at the design stage, otherwise, elements of the plates tightly fitted to each other will tightly clog the box of the house, creating unsuitable living conditions inside.

The technology of laying a ventilation system in a house from sip panels

In addition, houses made of sip panels have poor sound insulation. Styrofoam and expanded polystyrene inside the boards are not soundproof materials, on the contrary, they conduct well and sometimes increase impact noise.

Of course, if your frame house is in the wilderness, there is no need to worry about extra noise, but if the house is in a rather busy place, you will have to strengthen its interior with noise-absorbing material with your own hands.

How to choose a foundation for a frame house?

Despite the fact that laying the foundation for a house made of sip panels does not require large expenses (about 20% of the total construction budget), you still have to make efforts and ingenuity. The thing is that the box of the house has an unusually low weight, plus, it is necessary to take into account the specific features of the soil, climate conditions, the depth of groundwater of the building site.

The main nuance associated with these houses is seasonal heaving of the soil, after which the entire box of the house can shift, crack or tilt. The best options for the foundation for them can be called:

Screw piles- a simple, quickly mounted, cheap foundation. A screw pile is a steel tube to which a blade is attached, designed to be screwed into the soil. This foundation has a good bearing capacity, because in the process of screwing the blade into the ground, it does not loosen it, but, on the contrary, compacts it.
- rarely used technology. Unprofitable for developers, because it is suitable only for non-porous soils, while the rest will provoke its deformation after a season or two. To make such a foundation, it is necessary to remove 40 cm of soil, install a formwork with reinforcement and fill it with cement. The main disadvantage of such a foundation is the long drying of the concrete pour (up to a month). In addition, the underground of such a house will be ventilated much worse than in a pile house.
– a good option for slightly heaving soils. Its arrangement is a reinforced reinforced concrete thick slab lying on a bulk cushion. Such a foundation allows you to evenly distribute the load on the ground and protect the house from seasonal shifts.
- a good option for slightly heaving soil, much cheaper than a monolithic type. Such a foundation is a structure of separate slabs, located at the points of the corners of the future box of the house, at the junction of rooms and massive load-bearing beams.

How to do the installation of panels with your own hands?

Despite the fact that the procedure for building a frame house is simple and fast, in order to build it, you will need a lot of auxiliary tools, finishing materials and fasteners.

A careful calculation is made specifically in order to find out how much material will be spent on construction. This calculation should take into account all the locations of door and window openings, their width and height, as well as the thickness of all external and internal walls of the house and the place where communication networks are laid.

Panel country houses– installation technology

Do-it-yourself installation of panel houses is carried out as follows:

waterproofing (for example, roofing material) and a strapping beam impregnated with an antiseptic substance are laid on the existing base of the foundation;
on the strapping beam, with the help of screws, the starting boards are attached;
standard width of sip panels: 125, 250 and 280 cm. They are attached to each other using special grooves into which wooden dowels are inserted. Fastening should take place hopelessly, hermetically, with further blowing of the mounting foam, so that the future building does not let the cold through;
if the house is on a shallow base, the starter boards are attached to the composite panels, not the strapping.

Roof laying

Roof panel fastening scheme

Roof construction in panel house very easy to do by hand. In addition to the fact that in this case you do not need to do the crate, he himself roofing cake it also does not need to be assembled, because the sandwich panel is a finished element.

You just need to lay the sip panels on the rafters, fix them with self-tapping screws, and, leaving a small ventilation gap, cover with a roof. Bituminous tiles and metal tiles are best suited.

In addition, if you have the means and can afford the services of a light crane, assemble the roof on the ground with your own hands, and then install it in place with a crane.

Exterior and interior decoration of the house with sip panels

Finishing, both internal and external, is done very quickly. Since the panels are smooth and even, the finishing cladding does not need to be pre-screeded and plastered.

However, prior to installing the drywall and finishing, the joints between the panels must be sanded and patched with paint mesh. In addition, before carrying out any finishing work, it is necessary to make holes for communications.

In rooms with high humidity (bathroom, toilet), the joints are closed silicone sealant, and sip panels are overlapped in order to protect wall materials from getting wet. The floors in these rooms need to be additionally waterproofed or even laid with self-leveling acrylic floors.

Among the outdoor finishing methods, the most attractive are:

thin plastic vinyl siding panels do not rot and perfectly protect from moisture;
facade plaster- the most common finishing variation;
corrugated board- light finishing material made of metal, characterized by its strength, resistance to rust;
fiber cement is a strong, compressed slabs of cement (more than 90%) and cellulose.
facade tiles- a cheap and popular material that imitates natural finishing elements.

Thus, having considered all the nuances and features of building houses from sip panels, we can conclude that the positive characteristics of the material prevail over the negative ones.

In addition, the constant rise in the price of housing, especially apartments in cities, will soon make country frame houses the only way out for those who want to have personal real estate.

If you are looking to build warm house for little money, consider building a house from SIP (SIP) panels. The cost of a two-story "box" 10 * 10 meters without finishing - in the region of 17-20 thousand dollars. At the same time, there is no need for additional insulation, you can move into the house immediately after construction (if communications are connected) and you can immediately start finishing.

What is a SIP panel

The construction of houses from SIP panels began in the second half of the last century in Canada. The technology is simple, the construction of a building requires very little time (from two to three weeks, depending on the complexity of the project), it can only be cheaper, and even then not in all regions.

Houses are built from heat-insulating panels, which in themselves have sufficient strength. On the English language these panels are called SIP, which is an abbreviation of the following name: StructuralInsulated Panel. It translates as "Constructive Thermally Insulated Panel". It turns out, in theory, in Russian, the name of this material should sound like QFT. In reality, the usual transliteration is used (replacing English letters with Cyrillic). As a result, the name "SIP-panels" is in use.

This material consists of two, between which a layer of expanded polystyrene (polystyrene) is laid. It turns out a kind of sandwich (construction "multilayer sandwich"). Hence another name sandwich panels.

When building a house, there are two types of assembly:

In our country, the first option is the most popular. The wooden frame gives the building extra strength. The bearing capacity of sandwich panels and without a frame is more than enough for the construction of one-two-story private houses. But knowing that a solid wooden beam is at the heart of the house is reassuring. This technology has another plus - maintainability. In case of problems, you can remove the damaged panel and replace it with a new one, which is impossible with frameless technology.

Advantages and disadvantages

Like any technology new to our country, building a house from SIP panels has its adherents and opponents. Opponents have the most important argument - the unnaturalness of materials, the possibility of highlighting harmful substances. Indeed, these plates are composed of foam and OSB. Styrofoam is a familiar material and it is dangerous only during combustion. OSB has also been on the market for a long time, it is made from pressed large chips and wood chips. Resins containing formaldehyde are added as a binder. It is this binder that raises the most questions: formaldehyde is a strong poison and its presence in the atmosphere in large quantities causes poisoning.

Formaldehyde emissions should be controlled by SES (sanitary and epidemiological station), only safe building materials should be on sale. So if you decide to build a house from SIP panels, carefully choose the manufacturer - the quality of the material depends on his conscientiousness. The panels assembled on the German OSB company Egger ("Egger") are recognized as the highest quality and safest. Their formaldehyde emission is E1 (safe).

Extract from GOST R 56309-2014 (date of introduction 2015-07-01): “Depending on the content (emission) of formaldehyde, the boards are produced in emission classes E0.5, E1 and E2.”

At the same time, they easily tolerate high humidity, do not absorb water and do not deform.

SIP panel Egger E1 2800x625x174 (Romania) - the best option for walls. Height - 2800 mm, thickness of expanded polystyrene - 150 mm. If you prefer "standard" ceilings with a height of 2.5 meters, then you should purchase Egger E1 2500x1250x174

The German Glunz Agepan panels are also good, but few people use them. If we talk about Russian manufacturers, then you should pay attention to the products of the Kalevala company. In production, only safe and high-quality materials are used:

1. OSB-3 Kalevala Russia E1 emission class;
2. Glue - TOP-UR (Russia);
3. Expanded polystyrene - PSBS - 25C Knauf (Russia).

Speaking about the advantages of building from SIP panels, it is necessary to pay attention to the fact that the technology has been thoroughly developed. Panels are produced for various elements of the house: external walls, partitions, interfloor ceilings, etc.

Why do people build houses from SIP panels? Because such a house has solid advantages:

Light weight, which saves on the foundation. Under this type of buildings, pile or are ideal.
Small heat loss, low heating costs. Expanded polystyrene is an excellent insulation, and it is clamped on both sides with OSB sheets. This makes the sandwich panel house very warm.
Low cost per square meter.
Short construction time. A box of a two-story house can be assembled in a month.
No shrinkage. Sediment may be at the foundation. The construction of SIP panels has no draft.
Finishing work can begin immediately after the box is assembled.

In general, it is this set of properties that makes people choose a house from SIP panels. They build both houses of permanent residence and summer cottages for seasonal visits. So, at limited budget, building a house from SIP panels can be a very good way out.

How to build with your own hands

There are two ways to build a house from SIP panels with your own hands:

Buy a house kit for a specific project in a company that deals with this, and assemble it yourself. Not all firms agree to this, but many have a supervised installation service. This is when a company specialist controls your installation.
Buy plates. cut them under the right dimensions, buy timber, all this - on your own. In this case, the entire responsibility for the quality of construction will fall on you. If you have carpentry skills or you have someone to tell you, you can choose this option.

Briefly about what a house kit is. This is a set of ready-made SIP panels, wooden beam the right size and fasteners for the construction of a particular house. All components are cut at the factory, numbered. When assembling, you use the resulting blocks in a certain order. The process is reminiscent of building a house from a children's designer, only you are assembling a real house.

Building a house from SIP panels when ordering a house kit is like playing a constructor

Domokomplekt is good, if everything is done accurately. This is not only about the quality of SIP panels (it must be checked separately), but also about the use dry wood (chamber drying), and about the accuracy of the cut. The edges of the panels must exactly “grapple” the timber, the two panels must meet with an expansion gap of about 3 mm - all this is achieved using precision equipment.

Reference. The expansion gap is the required distance that is left between building materials subject to expansion (dilation). If a house is being built in a region with a humid climate (for example, the Leningrad Region), then it is imperative to leave an expansion gap, otherwise the OSB will be swollen. In dry climates, there is no need for a gap between OSBs.

Stages of construction: photo report

Building a house from SIP panels, like any other, begins with the selection and construction of a foundation. It is considered optimal for light houses pile foundation. That is what they do in most cases, starting building a house using SIP technology. Sometimes it is impossible to put a pile foundation:

on hard soils that are too expensive to drill (rocks);
on unstable soils with low bearing capacity (peat bogs);
in the presence of cavities in the rock mass.

In these cases, they do or (usually USHP - insulated Swedish stove). They are much more expensive, but more reliable.

After the foundation has been selected and calculated, its construction can begin.

We make a pile foundation

Since the foundation of screw piles is most often made, we will illustrate its manufacture. Piles are screwed into the ground manually (if the soil and strength allow) or with the help of special equipment. The height of the heads is 80 cm above the ground, the distance between the piles is not more than 2.5 meters.

Heads are welded to the installed piles, a strapping beam is attached to them (in this example, 200 * 200 mm).

Important! The joints of the beam must necessarily be on the heads. When laying the strapping beam, do not forget to coat the locks with a protective compound before joining ( bituminous mastic).

There is no support under the joint - you can’t do that!

To protect against decay and insects, the strapping timber is impregnated with a protective compound. Roofing material was laid under the timber (on the heads) in two layers.

This stage takes from 3-4 days to a week. Depends on the complexity of the soil, you work with the equipment or twist it yourself. Now you can start laying floor slabs, but before that, we should familiarize ourselves with the methods of their connection.

How to connect SIP panels: the basic principle

When connecting the panels, a wooden dowel (beam) and or a thermal dowel (a section of the SIP panel of a smaller thickness) is inserted between them. As mentioned above, in our country, the technology using a frame is more popular, i.e. dry timber is used as a dowel. It is on this option that we will focus our attention.

The beam is inserted into the groove and fixed with self-tapping screws and / or nails, which are twisted / hammered through the OSB into the body of the beam. In the presence of a nail gun, we initially recommend grabbing the panels with “yellow” wood screws 40-50 mm long, and then punching the joints ruffed nails 50-65 mm long in increments of 10-15 cm.

As fasteners for SIP panels, you can use: "yellow" wood screws, galvanized screw nails, galvanized ruff nails. Do not use "black" hardened self-tapping screws - they break off and quickly corrode

There is always a risk that the connection will turn out to be leaky, and the entire construction technology from SIP panels is based on the thermos effect, that is, on maximum tightness. Therefore, before assembling this assembly (and any other), mounting foam is applied to the side surface of the panel. It fills all the cracks, providing the proper level of heat and moisture insulation.

Note! The figure above shows a key from a double bar. Often, such recommendations are perceived incorrectly, and in order to save money, a non-planed edged board 50x150x6000 mm natural humidity. After the board dries, the connection is unlikely to remain airtight.

In the manufacture of a composite wooden key 100 * 150, in our opinion, it is preferable to use three dry bars with a section of 50 * 100 mm - in this case, the connections overlap (see video below).

If a we are talking about wall panels, it makes sense to insert and fasten the dowels in advance.

The foam was applied, a beam was inserted, secured with self-tapping screws. Foam was applied to the side face of the second plate, a groove was brought under the protruding part of the beam, an expansion gap of 3 mm was set, and secured with self-tapping screws. The foam that came out during the installation process from the seams is cut off after polymerization.

This technique is repeated with slight changes in any connection of SIP panels. The diagram of this node is presented above.

After cutting the plates, it becomes necessary to remove the expanded polystyrene to the required depth. For these purposes, an electric thermal knife (cutter) for foam is used. They come in various designs, but without fail, the thermal knife must be equipped with a limiter. Only in this case you will be able to remove the expanded polystyrene exactly to the required depth. "Brute force" is fraught with the fact that cold bridges may appear at the junction of the panels.

The cutter can be made by hand, but at the same time do not forget about safety precautions when working with electric current.

First overlap

The first floor is nothing more than a floor that does not require insulation. As melted, it is assembled from SIP panels 224 mm thick and 625 mm wide. With this width of the slabs, the wooden beams are arranged in increments of about 60 cm, which is enough to withstand the load.

If you have plates with a width of 1250 mm, then they must be cut lengthwise into two equal parts.

When installing the ceiling, the panels should be laid like bricks in the masonry - with a mismatch of the seams (in a row). This is necessary so that the seams do not warp with increasing humidity.

It is on such pieces that blocks for floors should be sawn when using slabs with a width of 1250 mm

To protect the lower OSB slab from moisture, each of the slabs on one side is smeared with the same bituminous mastic. You can use other compositions with similar properties.

Assembly of SIP floor panels on the first floor

When connecting the plates, a mounting bar is laid between them (diagram in the previous paragraph). The beam is attached along the edges to the strapping (with long nails), and the edges of the plates to it with self-tapping screws.

The side sections of the slabs (all floors) are closed with an edged board of a suitable size. We apply foam on the side surface of the plate with a snake, then attach the board, fasten it through the OSB with self-tapping screws into the end of the board.

On top of the sandwich around the perimeter, a starting (crown) board is laid, on which the wall SIP panels will rest. It is laid around the perimeter and in those places where partitions will be installed.

The crown boards are fastened with nails / self-tapping screws, but to be sure, they were fixed through with studs to the pile heads. Holes were drilled for the studs. A stud is driven into them, pulled together with bolts.

Walling

We continue to build a house from SIP panels: we mount the walls of the first floor. For this work, it is desirable to have two assistants, then the process will go faster and easier.

We put the first panel so that it “puts on” the crown board

Installation of walls begins from one of the corners. When installing, the panel with a recess in the lower part is “put on” on the installed starter board (pre-apply a layer of foam on the board or the end of the sandwich). The panel is placed, aligned vertically, attached to the starting board on both sides with self-tapping screws in increments of 10-15 cm.

Foam is applied to the side surface of the installed plate, another plate is set at an angle of 90 °. An embedded board (end bar) is pre-attached to its side part, the thickness of which is equal to the depth of the groove. Like the first, this panel is attached to the strapping starter board.

In addition, with the help of long self-tapping screws we fasten the corner.

As a rule, self-tapping screws with a length of 220 to 280 mm are used.

The length of the self-tapping screw must be such that it passes through the slab and the entire thickness of the embedded board. The installation step of this fastener is 40-50 cm.

in windows and doorways, for more reliable fastening, you can install metal perforated reinforced corners. The element is optional, but gives rigidity and inspires confidence.

Exterior walls and partitions are erected immediately

The installation of partitions from SIP panels occurs according to the same principle: we fasten the crown board, partition blocks to it. They can be the same thickness as for exterior walls, but thinner ones can also be used. The decrease in soundproofing properties is compensated by the interior decoration.

To save money, partitions can be made using frame technology. Then, initially, only the frame can be installed, and its lining can be transferred to a later period. It is more convenient to do this when the roof is already installed.

In the house of SIP panels, partitions can be made frame

Interfloor overlap

To install floor slabs in the grooves of wall panels, boards are installed on foam and self-tapping screws. They create a strapping for the installation of the ceiling.

Next, lay the floor slabs. If the partitions are assembled from SIP panels, their bearing capacity is quite high and additional measures reinforcement is not required. If the partitions were assembled using frame technology, we make the upper beams reinforced: they are assembled from three boards glued together. For greater strength, the beams can still be fastened on both sides with self-tapping screws.

Floor slabs from SIP panels are laid on the finished frame. They should be no more than 625 mm wide, they must be laid in a run-up (with mismatched seams). Since the panels are narrow, there is a lot of wooden beams in the ceiling. Due to this, such an overlap can withstand loads in places where there are no floor beams.

We fasten the laid plates to the strapping beam with self-tapping screws or nails. OSB edges - top and bottom to each intermediate beam. After fixing the installation of the ceiling, we close the open side sections along the perimeter of the building according to the same principle: foam + edged board. For greater rigidity, in those places where the floor beams pass, we fasten the floor panels long self-tapping screws(220 mm) through.

This stage after the assembly of the first floor does not seem difficult. Everything is the same, only work at height, tightening sandwich panels is longer and more difficult than mounting them.

Second floor walls

Second floor in this project- because the wall panels are low. Along with the outer walls, we also install partitions. Before installing the roof, a mortgage beam is installed in the upper open groove, roofing SIP panels will be attached to it.

Under the gables, standard panels will have to be cut, since the shape here is non-standard. Installation and connection of the wall panels themselves on the second floor is no different.

Roof made of SIP panels

For the roof, special sandwich panels are used. Under them, the ends of the plates are cut off at a certain angle, which is determined by the angle of inclination of the roof slope. Here, just as with flooring, you can get by with a minimum of beams, because each connection has its own beam. So truss system do not collect.

For a roof made of beam SIP panels, a minimum of

Skate decoration

The roof of a small and medium-sized house made of SIP panels usually has a central ridge beam. This is where the two roof planes meet. This node can be designed in two ways (in the figures below). The first one is symmetrical. Sandwich panels are cut at an angle, the top of the ridge beam is cut at the same angle. Two planes are fastened with long self-tapping screws through the panel to the beam on both sides. Fastener installation step - 30-40 cm.

In this method, there is no usual timber between the two plates, they are connected only to the foam. After the foam polymerizes, the excess is cut off, the seam is treated with a waterproof sealant, after which a protective strip is put on the ridge - made of metal, plastic, etc. - depends on the type of roofing chosen.

It is possible to dock roofing SIP panels on a ridge in a different way. The second method does not require cutting the slabs at an angle, but one part of the panels must be longer (by the thickness of the roofing slab). The beam is still cut at an angle, the plates are joined at a right angle, fastened through with long self-tapping screws to the beam.

In this connection, embedded end bars are used. They are installed as usual - on mounting foam and self-tapping screws. To block the access of moisture to the under-roof space, the junction of the two panels is also additionally coated with a waterproof sealant.

There is an option of mounting the roof from SIP panels and without a central beam. There are options for roofs with two load-bearing beams that are not located in the center. These can be either specially laid floor beams, or partitions assembled from SIP panels or using frame technology. In the second case, it is better to strengthen the beams (make them prefabricated with glue and nails).

In this knot, the most difficult thing is to cut the embedded bars at the right angle. This can be done on the ground, which greatly simplifies the task. The panels are fastened through the slab with long self-tapping screws to the floor beams or embedded in the partitions. Also, two planes are fastened together at the junction point - from opposite sides with long self-tapping screws.

Roof and wall panel connections

Under the laying of roofing SIP slabs, wall slabs are cut at the desired angle. Inner part OSB is obtained above the outer. At the same angle, the foam plastic is “cut”, the edges of the embedded beam are cut. It is this part that is the most difficult if you did not buy a house kit, and you build a house from SIP panels from standard panels, cutting them to the desired size with your own hands.

How to connect wall and roof SIP panels

With the appropriate equipment, it is not a problem to cut them at an angle. Trouble cut in between OSB boards foam to the desired depth. You can choose the core with a thermal knife, and then remove the residues in a purely mechanical way. Most likely, the cut will still not work out even, so you will have to add more foam to fill in the bumps.

In the drawings, the roof overhang is also made of slabs with insulation. It's easier to implement, but it's an unreasonable expense. To save, the length of the SIP panel is taken to the intersection with the walls, and then only the beam goes (as in the photo). In this case, the beam is made composite: one part is longer by the amount of overhang, the second is shorter and ends where the wall ends.

Features of joining roofing slabs

The connection of two roofing plates occurs in the same way as the others: timber, foam, self-tapping screws. But since precipitation is possible here, it is advisable to seal all seams.

To improve the tightness, all seams on the roof are additionally coated with a waterproof sealant. First, the frozen foam is cut into a plane with the roof, then a sealant is applied. After filing the overhangs, we can assume that the construction of the house from SIP panels is completed. Insert windows / doors, bring communications and the home is already habitable. Finishing can be done immediately after installing the box.

Mice and other troubles

To save our readers from unnecessary headaches, we decided to talk about the mistakes made during the construction of one residential building. First of all, the material is intended for those who hire contractors for the construction. However, it will be useful for those who build a house on their own.

The object was built under the "Country House" program, and local would-be builders acted as a contractor. Unfortunately, the future tenants did not pay due attention to the quality of the work. The result is natural - a large number of significant "jambs".

Brief information about the house:

Date of commissioning: 2008
Number of floors: 2
Foundation type: tape
Technology: frameless
Panel dimensions: 2740x1220x224 (ceilings), 2740x1220x174 (walls), 2740x1220x145 (key for connecting wall panels)

Problems emerged rather quickly and were associated with the most important part of any structure - the foundation. Strip foundation was filled with poor quality concrete, this led to the fact that when moisture got in, it began to crumble.

In extreme cold (below -30°C), another “jamb” was revealed - a part of the plastic floor plinth in the kitchen froze through.

It was decided to remove the lower panels of the vinyl siding, remove the cold bridges at the junction of the wall slabs with the ceiling of the first floor, and sheathe the foundation with a profiled stone-like sheet.

After dismantling the lower panels of the siding, there were signs of the vital activity of field mice.

During construction, the ends of the ceiling were not covered with a board. Pieces of plywood are installed, between which there are large distances. Also note that the roofing material does not start from the beam, but from the floor level

Brief explanation of ruberoid. At the time of the construction of the house, in a particular locality, they had not heard of vapor-permeable membranes. The contractor was going to lay plastic sheeting on the walls. The customer opposed this, as a result, roofing material was used.

It is perfectly clear that the mice did not waste time in vain ...

As a result, the owner of the house had to level the consequences using his modest building experience.

Related errors:

The lower part of the first floor ceiling has not been treated with bituminous mastic.
SIP-panels 1220 mm wide were laid on the floors of the first and second floors (they had to be cut in half lengthwise).
Used raw wood.
The panel for making thermospins is thinner than the styrofoam layer.
The corners of the house are not tightened with long self-tapping screws.
Self-tapping screws are exclusively black.

There were other errors, but we do not talk about them, because they do not directly relate to the construction technology of SIP houses.

Alas, the case discussed above is not the most difficult - the fatal option is discussed in the video below.

The conclusion is very simple: you should not blindly trust the customer. All stages of construction must be controlled personally, or seek the help of a knowledgeable person from the outside.

If contractors are involved in the construction, then the quality of their work can be assessed already at the stage of acceptance of the floor of the first floor.
